Blue Mackerel
The blue mackerel (''Scomber australasicus''), also called Japanese mackerel, Pacific mackerel, slimy mackerel, or spotted chub mackerel, is a fish of the family (biology), family Scombridae. Description The blue mackerel typically reaches in fork length. It can reach in fork length and in weight. Mackerels have a round body that narrows into the tail after the second dorsal fin, similar to a tuna fish. Blue mackerel are often mistaken for chub mackerel. In fact, blue mackerel were believed to be a subspecies of chub mackerel until the late 1980s. Though they are both in the same genus (''Scomber''), blue mackerel set themselves apart by differing structural genes than those of the chub mackerel. Other, more obvious, characteristics set these two apart, like the longer anal spine of the blue mackerel, and the amount of spines on the first dorsal fin. Distribution and habitat The blue mackerel is found in tropical to subtropical waters of the Indian Ocean, Indian and Pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georges Cuvier
Jean Léopold Nicolas Frédéric, baron Cuvier (23 August 1769 – 13 May 1832), known as Georges Cuvier (; ), was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastr ...

Hawaii
Hawaii ( ; ) is an island U.S. state, state of the United States, in the Pacific Ocean about southwest of the U.S. mainland. One of the two Non-contiguous United States, non-contiguous U.S. states (along with Alaska), it is the only state not on the North American mainland, the only state that is an archipelago, and the only state in the tropics. Hawaii consists of 137 volcanic islands that comprise almost the entire Hawaiian Islands, Hawaiian archipelago (the exception, which is outside the state, is Midway Atoll). Spanning , the state is Physical geography, physiographically and Ethnology, ethnologically part of the Polynesian subregion of Oceania.

Hawaiian Language
Hawaiian (', ) is a critically endangered Polynesian language of the Austronesian language family, originating in and native to the Hawaiian Islands. It is the native language of the Hawaiian people. Hawaiian, along with English, is an official language of the U.S. state of Hawaii. King Kamehameha III established the first Hawaiian-language constitution in 1839 and 1840. In 1896, the Republic of Hawaii passed Act 57, an English-only law which subsequently banned Hawaiian language as the medium of instruction in publicly funded schools and promoted strict physical punishment for children caught speaking the Hawaiian language in schools. The Hawaiian language was not again allowed to be used as a medium of instruction in Hawaii's public schools until 1987, a span of 91 years. The number of native speakers of Hawaiian gradually decreased during the period from the 1830s to the 1950s. English essentially displaced Hawaiian on six of seven inhabited islands. In 2001, native ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognate
In historical linguistics, cognates or lexical cognates are sets of words that have been inherited in direct descent from an etymological ancestor in a common parent language. Because language change can have radical effects on both the sound and the meaning of a word, cognates may not be obvious, and it often takes rigorous study of historical sources and the application of the comparative method to establish whether lexemes are cognate. Cognates are distinguished from loanwords, where a word has been borrowed from another language. Name The English term ''cognate'' derives from Latin , meaning "blood relative". Examples An example of cognates from the same Indo-European root are: ''night'' ( English), ''Nacht'' ( German), ''nacht'' ( Dutch, Frisian), ''nag'' (Afrikaans), ''Naach'' ( Colognian), ''natt'' ( Swedish, Norwegian), ''nat'' ( Danish), ''nátt'' ( Faroese), ''nótt'' ( Icelandic), ''noc'' ( Czech, Slovak, Polish), ночь, ''noch'' ( Russian), но� ...

Māori Language
Māori (; endonym: 'the Māori language', commonly shortened to ) is an Eastern Polynesian languages, Eastern Polynesian language and the language of the Māori people, the indigenous population of mainland New Zealand. The southernmost member of the Austronesian language family, it is related to Cook Islands Māori, Tuamotuan language, Tuamotuan, and Tahitian language, Tahitian. The Māori Language Act 1987 gave the language recognition as one of New Zealand's official languages. There are regional dialects of the Māori language. Prior to contact with Europeans, Māori lacked a written language or script. Written Māori now uses the Latin script, which was adopted and the spelling standardised by Northern Māori in collaboration with English Protestant clergy in the 19th century. In the second half of the 19th century, European children in rural areas spoke Māori with Māori children. It was common for prominent parents of these children, such as government officials, to us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cat Food
Cat food is food specifically formulated and designed for consumption by cats. During the 19th and early 20th centuries, cats in London were often fed horse meat sold by traders known as Cats’ Meat Men or Women, who traveled designated routes serving households. The idea of specialized cat food came later than dog food, as cats were believed to be self-sufficient hunters. French writers in the 1800s criticized this notion, arguing that well-fed cats were more effective hunters. By the late 19th century, commercial cat food emerged, with companies like Spratt producing ready-made products to replace boiled horse meat. Cats, as obligate carnivores, require animal protein for essential nutrients like taurine and arginine, which they cannot synthesize from plant-based sources. Modern cat food is available in various forms, including dry kibble, wet canned food, raw diets, and specialized formulations for different health conditions. Regulations, such as those set by the Associatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Otolith
An otolith (, ' ear + , ', a stone), also called otoconium, statolith, or statoconium, is a calcium carbonate structure in the saccule or utricle (ear), utricle of the inner ear, specifically in the vestibular system of vertebrates. The saccule and utricle, in turn, together make the ''otolith organs''. These organs are what allows an organism, including humans, to perceive linear acceleration, both horizontally and vertically (gravity). They have been identified in both extinct and extant vertebrates. Counting the annual growth rings on the otoliths is a common technique in estimating the age of fish. Description Endolymphatic infillings such as otoliths are structures in the saccule and Utricle (ear), utricle of the inner ear, specifically in the Labyrinth (inner ear), vestibular labyrinth of all vertebrates (fish, amphibians, reptiles, mammals and birds). In vertebrates, the saccule and utricle together make the ''otolith organs''. Both statoconia and otoliths are used as gra ...

East Australian Current
The East Australian Current (EAC) is a warm, southward, western boundary current that is formed from the South Equatorial Current (SEC) crossing the Coral Sea and reaching the eastern coast of Australia. At around 15° S near the Australian coast the SEC divides forming the southward flow of the EAC. It is the largest ocean current close to the shores of Australia. Behaviour The EAC reaches a maximum velocity at 30° S, where its flow can reach 90 cm/s. As it flows southward it splits from the coast at around 31° to 32° S. By the time it reaches 33° S it begins to undergo a southward meander while another portion of the transport turns back northward in a tight recirculation. At this location the EAC reaches its maximum transport of nearly 35 Sv (35 billion liters per second). The majority of the EAC flow that does not recirculate will move eastward into the Tasman Front, crossing the Tasman Sea just north of the cape of New Zealand. The remainder will flow so ...

Retina
The retina (; or retinas) is the innermost, photosensitivity, light-sensitive layer of tissue (biology), tissue of the eye of most vertebrates and some Mollusca, molluscs. The optics of the eye create a focus (optics), focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception. The retina serves a function which is in many ways analogous to that of the photographic film, film or image sensor in a camera. The neural retina consists of several layers of neurons interconnected by Chemical synapse, synapses and is supported by an outer layer of pigmented epithelial cells. The primary light-sensing cells in the retina are the photoreceptor cells, which are of two types: rod cell, rods and cone cell, cones. Rods function mainly in dim light and provide monochromatic vision. Cones function in well-lit conditions and are responsible fo ...
